It seems DVD-shrink has an ace algorithm for reducing DVDs with minimal
quality loss.

DVDs are just MPEG files...

So I wonder, is there a tool that will apply the same shrink to an
MPEG?

MPEG2 files.. there is a difference!


Yes. Some codecs have both encoding and decoding. You can always
re-encode the stream but that will introduce loss of quality. It's must
better if you can encode the material to lower bitrate to begin with as
MPEG (1/2/4) are lossy compression algorithms.

Transcoding is probably the best choise for you as it re-uses the
information, this helps most in reducing the time it takes to process
the stream.
